Network view parameters (Duplex)

Use the
Network
 view to view information about the Device Level Ring (DLR) network or the Parallel Redundancy Protocol (PRP) network.
The parameters are only available when the application is online, and there is no communication error in the device profile. Parameters that appear depend on whether the module profile is online to a DLR device or a PRP device.
WARNING:
PRP/DLR or IP Address switch positions do not match the physical device
setting.
This warning appears when the:
  • DLR or PRP mode switch changes during runtime
  • IP rotary switches change during runtime
Device Level Ring settings
Parameter
Description
Network Mode
Shows that the device profile is online to a Device Level Ring (DLR) device.
Network Topology
Displays the current network topology as either:
  • Linear/Star
    , or
  • Ring
Network Status
Displays the current network status as:
  • Normal
  • Ring Fault
    , or
  • Unexpected Loop Detected
Supervisor Status
Displays the status of the supervisor. Only available when
Supervisor Mode
 is enabled. Available values:
  • Active
     - Device is the Active Ring Supervisor
  • Backup
     - Device is the backup ring supervisor
  • Cannot support current Beacon Interval or Timeout
     - Device cannot support either the Beacon Interval or Beacon Timeout values of the current Active Ring Supervisor
Active Ring Supervisor
Displays the IP Address or MAC Address of the Active Ring Supervisor.
Only available when the device is in a Ring network.
Active Supervisor Precedence
Displays the precedence currently assigned to the active ring supervisor.
Only available when the device is in a Ring network.
Ring Faults Detected
Displays the number of ring faults detected on the network since the last power cycle or counter reset.
Only available when the device is a ring supervisor.
Last Active Node on Port 1
Displays the IP address or MAC ID of the last node the active ring supervisor can communicate with on Port 1 when a ring fault has occurred.
Only available when the device is a ring supervisor.
Last Active Node on Port 2
Displays the IP address or MAC ID of the last node the active ring supervisor can communicate with on Port 2 when a ring fault has occurred.
Only available when the device is a ring supervisor.
Ring Fault Status
Displays the current condition of the ring fault as either:
  • Partial network fault
    , or
  • Rapid fault/restore cycles
Only available when the device is a ring supervisor.
Enable Supervisor Mode
Indicates that the device is configured as a supervisor on the network. If cleared, the
Supervisor Mode
 is disabled, and the device is not a supervisor on the network.
Reset Ring Faults
Used to reset the device's ring fault count to zero.
Only available when the device is a ring supervisor.
Verify Fault Location
Causes the device to verify the last node fault location on port 1 and port 2 and update the
Last Active Node
 parameters.
The
Last Active Node
 parameters show information from the last fault until verification of the fault location.
Only available when the device is a ring supervisor.
Clear Rapid Fault
Causes the device to clear the Rapid Faults/Restore Cycles fault.
Only available when the device is a ring supervisor and the ring fault condition is
Rapid Fault/Restore Cycles
.
Refresh
Retrieves and displays the latest information from the device.
Advanced Configuration
Opens
Advanced Network Configuration
 to configure advanced network properties.
Parallel Redundancy Protocol settings
The Parallel Redundancy Protocol requires two separate physical networks to operate. These networks are labeled LAN A and LAN B.
Parameter
Description
Network Mode
Shows that the device profile is online to a Parallel Redundancy Protocol (PRP) device.
Last PRP Fault Timestamp - Port A
Displays the timestamp of the last fault for port A.
None
 displays when there is no fault for the port.
Tip:
 To ensure the correct timestamp appears, enable the Precision Time Protocol and synchronize the adapter.
Last PRP Fault Timestamp - Port B
Displays the timestamp of the last fault for port B.
None
 displays when there is no fault for the port.
Tip:
 To ensure the correct timestamp appears, enable the Precision Time Protocol and synchronize the adapter.
Diagnostics for other PRP nodes
Displays the list of PRP devices detected by the device and the LAN(s) they were detected on.
Address
Displays the node's IP Address or MAC Address.
Node Type
Specifies the node's operating mode.
  • Double Attached Node (DAN)
  • Virtual Double Attached Node (VDAN)
  • Redundancy Box Node (RedBox)
Port A
Displays the status of the node on LAN A.
  • Active
  • Inactive
Port B
Displays the status of node on LAN B.
  • Active
  • Inactive
Diagnostics
Displays counters and status information for each LAN.
Network Status
Displays the state of the LAN.
  • OK
     - indicates that there is no problem with the PRP network
  • Fault
     - indicates that there is a problem with the PRP network
Network Fault Count
Displays the number of times the
Network Status
parameter has changed from
OK
to
Fault
since the last Reset Counters operation or powerup.
Transmit Count
Displays the number of PRP-tagged frames transmitted over each LAN since the last Reset Counters operation or powerup.
Receive Count
Displays the number of PRP-tagged frames received on each LAN since the last Reset Counters operation or powerup.
Wrong LAN Count
Displays the number of PRP-tagged frames received on the wrong LAN since the last Reset Counters operation or powerup. For example, a LAN A PRP-tagged frame is received on LAN B (or vice versa).
Usually indicative of a wire cross-connected from LAN A to LAN B.
Unique Entry Count
Displays the number of PRP-tagged frames received on one LAN, but not received on the other LAN, since the last Reset Counters operation or powerup.
Usually indicative of a loss of connection or loss of frames on the other LAN.
Duplicate Entry Count
Displays the number of PRP-tagged frames received on this LAN that were already received on another LAN since the last Reset Counters operation or powerup.
Tip:
 This count increments during normal operation, and is not an indication of a fault.
Multiple Entry Count
Displays the number of PRP-tagged frames for which multiple duplicates were received on each LAN since the last Reset Counters operation or powerup.
Usually indicative of a miss configured network (such as a routing loop).
Refresh
Retrieves and displays the latest information from the device.
Reset Counters
Sets the PRP counter values to zero and then refreshes the values displayed on the tab with the current counter values.
